A finial is a carved stone element, typically placed at the apex or terminating point of a gable, spire, or roof ridge, and this particular one once crowned some part of the medieval church that still stands, roofless, within the graveyard. It was not found in any tidy architectural context but turned up in 1956 roughly four metres outside the south-western section of the graveyard wall, lying in the ground some distance from where it would originally have been fixed. How it came to be there is unrecorded.

The piece is made from granite and is substantial in size, measuring 0.6 metres wide, 0.42 metres thick, and 0.47 metres deep. Its lower portion tapers to a blunt point, the kind of rough shaping that suggests functional stonework rather than purely decorative carving, and both arms have a rectangular cross-section that finishes in a flat vertical face. Interestingly, there appears to be decoration on the underside, though its exact nature is not fully documented. After its discovery, the fragment was moved for safekeeping and placed inside the mausoleum of Edward Byrne, a later burial structure situated at the eastern end of the church and graveyard enclosure. The medieval church it came from is recorded in the Sites and Monuments Record under the reference DU021-034002-, with the associated graveyard recorded separately as DU021-034003-.

Saggart village lies just off the N81 road, and the church and graveyard are accessible without great difficulty. The mausoleum housing the fragment sits at the eastern end of the complex, so it is worth walking the full length of the site rather than stopping at the more immediately visible ruined walls. The decoration on the underside of the finial is the detail most worth looking for, though it requires crouching or careful positioning to examine properly. Graveyards in Ireland often accumulate displaced architectural elements like this, pieces quietly relocated over generations, and this fragment is a good example of the way medieval stonework tends to survive more by accident than by design.
